SHOE-HEEL WEAR-RESISTING AND ANTJESLIFJPING DEVICE,

Specification of Letters Patent.

Patented Nov. id, 191%.

Application filed January 20, 1919. terial No. 272,0t1.

Wear-Resisting and Antislipping Devices,

and l do declare the following to be a' full, clear, and exactdescription of the invention, such aswill enable others skilled in theart to which it appertains to make and use the same.

My invention has for its object to provide an extremely simple andinexpensive, yet highly efficient and durable device for embedding inrubber and fiber heels to resist wear and to prevent slipping; and withthis object in view, the invention resides in the novel features ofconstruction and unique association of parts herein fully described andclaimed.

Figure 1 of the accompanying drawing is a bottom plan viewof a heel andthe invention embedded therein.

Fi 2 is a vertical section on the plane of the line 22 of Fig. l.

Figs. 3 and 4: are detail transverse sections on the planes designatedby the lines 33 and. M, respectively, of Fig. 2.

Fig. 5 is a perspective view of the wear resisting and anti-slippingdevice. j

Fig. 6 is an elevation of the plate from which the device is formed.

in the manufacture of the invention, an elongated metal plate 1 has oneof its ends 2 bent laterally and provided with a notch 3, whereby a pairof calks 4: are formed, for disposition at the tread surface of the heelas shown. The other end 5 of the plate 1 is bent laterally in the samedirection as the end 2 and at 6 is further bent outwardly at rightangles to provide a wear resisting plate whose surface is by preferenceroughened at 7.

Fhe device is embedded in a .rubber or fiber heel .8 with the calks 4and the wear plate 6 exposed at the tread of said heel, said plate beinglocated at the point liable to receive most wear.

in order to permit edective anchorage of the device, an opening 9 ispreferably formed in the body portion of the plate 1 and in its bent end5, so that the rubber-or material on opposite sides of said body portionmay be united by the material within said opening, and it will beobserved that the same result is obtained by the provision of the notch3.

By constructing the device in the manner shown or in any adequate mannerwhich in cludes a body or anchor member, calk means at one end of saidanchor member, and a wear plate joined to the other end thereof,

a highly efiective device is provided, sincewhen the weight of the useris placed upon the heel and the latter compresses, the plate 6 has atendency to force upwardly on the rear end of the device thus slightlycanting the latter and tending to project the calk means 4 foranti-slipping purposes. It also will be observed that the merecompression of the heel will expose the calks for proper operation; andthe roughened lower surface 'of the plate 6 will also assist materiallyin preventing slippage.

Since probably the best results are obtained from the details shown anddescribed,

they may well be followed, but within the scope of the invention asclaimed, numerous minor changes may well be made.

What is claimed is:

1. In a wear resisting and anti-slipping device for cushion heels, anelongated plate havin one end bent laterally and formed to providerelatively sharp calks, the other end of said plate being bent laterallyin the same direction and further bent outwardly at right angles to thelaterally bent portions to form a wear plate.

2. In a Wear resisting and anti-slipping device for cushion heels, anelongated plate having one end bent laterally and notched to providecalk means, the other end of said plate being bent in the same directionand further bent outwardly at right anglesto form a Wear plate.

3. In a wear resisting and. anti-slipping device for cushion heels, adevice formed of a strip of sheet metal having substantially paralleledges and being formed 'with a longitudinal aperture, one end of thestrip being formed with. a notch and turned at right angles to themiddle portion so as to tioned bend and the adjacent end of the formrelatlvely sharp calks, the other end strip to form a wear plate whichlies subportion of the strip being formed with a stantially in a planeparallel with that of 10 .bend at right angles to the middle portion,said middle portion.

said bend being at a line intersect ng the In testimony whereof Ihave-hereunto set said aperture, the strip being further promy hand.vided with a bend between the first men- BLAIR HARDESTY.
